What is the similarities and differences of physical and chemical weathering?
While physical weathering breaks down a rock's physical structure, chemical weathering alters a rock's chemical composition. Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.
What is the similarity of physical weathering and chemical weathering?
Their Similarities They both made rocks and other sediments have cracks in them. Physical and Chemical Weathering made sediments into soil.
What are some similarities and differences between physical and chemical weathering quizlet?
Physical weathering is the breakdown of large rocks into fragments by physical forces; the chemical composition of the rock is not changed. Chemical weathering is the breakdown of rock by chemical reactions; the chemical composition is changed.
What are three differences between chemical and physical weathering?
In this weathering, some or all of the minerals in the rocks suffer decay or alteration and transform into different chemical combinations. Agents of physical weathering include temperature changes, moisture, frost action and wind. Agents of chemical weathering include water, oxygen, carbon or various organic acids.
What are 3 similarities between physical and chemical changes?
What are the similarities of physical change and chemical change?
| Physical Change | Chemical Change |
|---|---|
| A Physical change affects only physical properties i.e. shape size etc. | Chemical change both physical and chemical properties of the substance including its composition |

What is the similarity and difference of physical weathering?
These processes initiate a change in a rock's appearance or composition. However, physical weathering changes the rock's appearance through physical changes like abrasion; while in chemical weathering, chemical reactions that happen in the environment change the rock's appearance and composition.
What is the difference between physical and chemical weathering quizlet?
Rocks are chemically weathered when a chemical reaction takes place between a rock and another chemical. The difference is that physical weathering is a process that weathers rock without a chemical reaction or change. Chemical weathering changes the identity of rocks and it involves a chemical reaction or change.
What is the difference between physical and chemical changes?
In a physical change, no new substance is formed. A chemical change is always accompanied by one or more new substance(s). Physical change is easily reversible i.e original substance can be recovered. Chemical changes are irreversible i.e. original substance cannot be recovered.
What is similarities between physical and chemical change?
Similarities between physical and chemical changes are: In a physical change, only the physical properties such as shape, size, color, etc. are changed. In a chemical change, the chemical properties are changed such as basicity, acidity, etc.
How are they similar different chemical and physical changes?
When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged. When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances. Physical change is a temporary change.
How are physical and chemical changes similar 2 points?
Answer and Explanation: Physical and chemical changes are alike because they are both types of changes that can occur in various forms of matter.
What is the difference between physical and chemical reactions?
Physical changes are reversible and do not produce a new substance. Chemical changes result in the production of a new substance and cannot be reversed.
What are the 5 differences between physical and chemical changes?
Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Many physical changes are reversible if sufficient energy is supplied. The only way to reverse a chemical change is via another chemical reaction.
How are physical and chemical change alike?
Answer and Explanation: Physical and chemical changes are alike because they are both types of changes that can occur in various forms of matter.
